Description
This is a follow-up task for the fix in JDK-8370572 which needs to be delivered to the customer as quick as possible.

Comments
Fix Request (Openjdk 25u): Please allow this test-only change for OpenJDK 25u which includes a critical regression test for JDK-8370572 waiting for approval as well. Container tests pass on linux x86_64 cgroups v1 and cgroups v2 systems (the new test is skipped on cgroups v2). Patch from JDK 26 applies clean. I intend to integrate closely after JDK-8370572. JDK-8371769 would be a follow-up test fix after this is in.

[~sgehwolf], from a quick look, your test looks fine and is similar to what I proposed. Fell free to assign this issue to yourself and create a PR with your test.

[~simonis] Are you still working on this? I needed something for JDK-8365606 so I've written this: https://github.com/jerboaa/jdk/commit/65e3d52c901eee5c201b545c3f85a51cac2880da It's failing prior the fix of JDK-8370572 and passing after (on cg v1). Skipped on cg v2.
